ing through the plug ill into the chamber 250', and each of these portsis of greater diameter than the small end of the nozzle hole leadingfrom said chamber. This arrangement breaks the strength of the currentand avoids clogging of the nozzle hole. In other words, if the nozzlehole were presented directly to the force of the current in the chamber(5, the current or suction in the nozzle hole would be so great that aleaf or other rubbish would (-ovcr and be held against the opening atthe nozzle'and prevent further flow. This situation is relieved byproviding the ports 32 of greater capacity opening into the chamber 30to break the force of the current, and it a leaf or other rubbish coversone of the ports- 32, the current will pass through the others. Anyrubbish that should pass through the ports will be caught by the screen33 and can be easily removed by taking out the screwplug 31..

Having thus descr had our invention, we claim:

1. 1n a lubricating device for a turbine such as described, a feed headhaving a chamber formed therein with ports to the runner of the turbine,a bearing for the rotating shaft of the turbine also formed in said headand a nozzle screw threaded into a recess in said head forming an inletof gradually increasing-diameter to admit the actuating medium to saidhearing from said chamber, substantially as described 2. In alubricating device for a turbine such as described, a casing having feedand exhaust heads with bearings tor the driving shaft, said shaft havinga lungitudinal conduit therein, with radial openings to the bearing inthe exhaust head and channels in the face of the rear end thereof to thebearing in the feed head and an inlet thereto to admit the actuatingmedium from said chamber, substantially as described.

3. In a lubricating device for a turbine such as described, a feed headhaving chamber forn'ied therein with ports to the runner of the turbine,a removable bushing seated in a recess of the head forming a bearing forthe turbine shaft and a removable screw threaded nozzle adapted to admitthe z lctuating medium to said bearing and to force the bushing from itsseat, substantially as described. 4-. In a lubricating device for aturbine such as described, a feed head forming a feed chamber with portsto admit the actuating medium to the runner of the turbine, a bearingfor the shaft of the turbine formed in said head and a screening chamberalso formed in said head and having. openings to admit the actuatingmedium to said bearing from the feed chamber, substantially asdescribed.

5. In a lubricating device for a turbine such as described, a feed headwith a feed chamber having ports to the runner ot' the turbine, saidhead also having a bearing for the turbine shaft and a portion extendinginto said teed chamber forming a screening chamber having an opening tothe bearing and a plurality of ports opening from the feed chamber tothe screening chamber, each of said ports being of greater capacity thanthe opening from the screening chamber to the bearing, substantially asdescribed.

6. In a lubricating device for a turbine such as described, a feed headwith a feed chamber formed therein with ports to admit the actuatingmedium to the runner of the turbine, said head also having a bearing torthe turbine shat't formed therein and a ellow portion extending intosaid feed ch her with a removable plug forming. a screen ing chamberhaving a removable nozzle opening from the screening chamber to thebearing, said plug having a plurality of ports to admit the actuatingmedium from the feed chamber to the screening chamber, each of saidports being of greater capacity than the nozzle opening, substantiallyas described. 1

7. In a lubricating device for a turbine such as described, a turbinerunner with a driving shaft rotating therewith having conduitstherethrough to the bearings therefor, acasing having feed and exhaustheads forming feed and exhaust chambers with ports for the runner, saidheads also having bearings for the shaft on oppositesides of therunnerwvith spiral grooves therein, and the feed head a hollow portionextending into the feed chamber with a removable plug forming ascreening chamber having a removable screen therein, a removable nozzleforming an opening from the screening chamber to said" conduits, saidplug, l1aving a plurality of ports from the feed chamber to thescreening chamber, each of said ports being of greater capacity thansaid nozzle opening, substantially as described.
